Tta upconversion photocatalysis
WebThis paper reports a new class of visible light water splitting photocatalysts based on a triplet–triplet annihilation (TTA) upconversion (UC) process. The TTA-UC core composed of platinum-octaethyl-porphyrin (Pt(OEP)) and 9,10-diphenylanthracene (DPA) can upconvert low energy green light to high energy blue light with a high quantum yield.
